SDLMESS is a fork of MESS, the Multiple Emulator Super System, to SDL, resulting in a mostly platform independent version.

As the name suggests, this includes dozens of emulators for game consoles and home computers alike, from the PDP1 to the PlayStation.

As the sister project of SDLMAME, they share code and are always released at the same time. All graphical front-ends for SDLMAME support SDLMESS as well. It acts as a replacement for the seemingly dead xmess although no code was taken over from there.
